摘要：

The dimeric compound [Pd(dmba)(mu-Cl)](2) (1) (dmba = N,N-dimethylbenzylamine) reacts with KX, in methanol/acetone, affording the analogous dimeric pseudohalide-bridged species [Pd(dmba)(X)](2) [X = NCO(2), SCN(3), CN(4)]. The compounds were characterized by elemental analysis, infrared spectroscopy, NMR and thermogravimetric analysis. The IR data for 2-4 showed bands typical of coordinated pseudohalide ligands indicating clearly the occurrence of the exchange reaction. Their thermal behavior was investigated and suggested that their thermal stability is influenced by the bridging ligand. The thermal stability decreased in the order [Pd(dmba)(mu-SCN)](2) > [Pd(dmba)(mu-Cl)](2) > [Pd(dmba)(mu-NCO)](2) > [Pd(dmba)(mu-CN)](2). The X-ray results showed the formation of PdO as final decomposition product. (C) 1998 Elsevier Science Ltd. All rights reserved.
